What pretreatment is best for my application?

Iron phosphate is the most frequently used pretreatment for powder coating. It can be used with almost any substrate. Powder coatings will often give improved performance compared to liquid paint over the same pretreatment. For "high end" applications, zinc phosphate may be the pretreatment of choice. However, this process is more costly to operate, uses heavy metals, and can produce considerable sludge. The washer typically requires added stages versus an iron phosphate washer. If you cannot achieve the desired performance with iron phosphate, zinc phosphate or an improved paint system may be your only choice.
